How to Choose a Gas Grill: What Actually Matters buyers have more options than ever. Gas grills range from $150 to $5,000 and the price doesn't always align with performance. Knowing what actually affects cooking results versus what's marketing helps you skip the regret of buying the wrong grill.
More BTUs does not mean better grilling. BTU ratings measure fuel consumption, not heating efficiency. A well-designed 30,000 BTU grill will outperform a poorly designed 60,000 BTU one every time. What actually matters is BTU-per-square-inch: 80–100 BTU per square inch of cooking surface is the sweet spot. Below that and you struggle to sear; above and you're burning fuel for no benefit.
More burners = more cooking zones. Two burners let you do simple two-zone cooking (direct/indirect). Three or more burners let you do true indirect cooking for roasting and smoking, a dedicated searing zone, and a low simmer zone simultaneously. For families who grill regularly, three burners is the practical minimum.
Stainless steel grates: low maintenance, durable, don't rust, but don't retain heat as well. Cast iron grates: excellent heat retention and sear marks, but require seasoning and rust if neglected. Porcelain-coated grates: easy to clean and rust-resistant, but chips expose metal that rusts. For most people, stainless grates are the practical long-term choice.
Manufacturers love to advertise total cooking area including warming racks — those upper racks are useless for primary grilling. Focus only on the primary cooking area. For two people: 300–400 sq inches is enough. For a family of four grilling frequently: 400–600 sq inches. For large gatherings: 600+ sq inches.
Lid thickness is the most reliable visible durability indicator — a thin stamped steel lid warps quickly and loses heat. A heavy lid with solid hinges signals quality construction throughout. Look at the burner material: stainless steel burners outlast stamped steel ones by years. Weber, Broil King, and Napoleon build lids that hold up a decade; many budget brands don't make it five years.
For a standard two-burner grill with 400 sq inches of cooking area: 20,000–25,000 BTUs total (50–60 BTU per sq in). For a three or four-burner grill: 30,000–45,000 BTUs. Focus on burner construction and heat distribution over raw BTU numbers.
Weber Genesis and Spirit series lead in long-term reliability. Broil King and Napoleon offer comparable quality at similar price points. All three have strong parts availability and customer service — important when you're keeping a grill for 10+ years.
